I missed the boat on this thread first time around. But for anyone else looking for same higher end tools, more specific high end hex drivers, I recommend the Thorp drivers made by MIP. I have the 1.5, 2, 2.5mm set and wouldn't go near an RC vehicle without them. Over the years I have rounded off, bent and broken dozens of hex wrench's. Spending far more on junk then then I did on my MIP's. And other than cost, better drivers come with so much less frustration it makes working on small RC's enjoyable.
